Cavity Wall Insulation
With around 33% of the heat you pay escaping through the walls of your home, the value of quality cavity wall insulation is clear.
Cavity wall insulation is an easy and simple way to keep heat where you want it the most – indoors.
A typical detached house with cavity wall insulation can save up to £250 each year on heating bills
Our expert technicians can complete the job quickly and mess-free – with most being completed within a couple of hours. We are BBA accreditated and all of our work carries a 25-year CIGA Guarantee.
If your home was built after 1920, the chances are that its external walls are made of two layers with a gap or cavity between them. Cavity wall insulation fills that gap, keeping the warmth in to save energy. It can also help reduce condensation inside the house if this is a problem on your external walls.
Your home will usually be suitable for cavity wall insulation if:
- its external walls are unfilled cavity walls
- your cavity is at least 50mm wide
- the masonry or brickwork of your property is in good condition
- it is more than ten years old (most newer houses will have insulation already)
- the walls are not exposed to driving rain.
How Direct Savings can help
The Direct Savings free Home Health Check will allow us to assess how energy efficient your home is – and to decide whether you would benefit from cavity wall insulation.
Our extensive, 10 year experience as one of the UK’s leading energy efficiency specialists means we are ideally placed to source the best possible funding option for your cavity wall insulation – in some cases that could mean free cavity wall insulation.
How it works
To insulate your cavity walls, we drill small holes around 22mm in size at intervals of around 1m in the outside wall of your home. With specially designed equipment, we then blow insulation material into the cavity. Once all the insulation is in, we fill the holes in the brickwork so you'll barely notice them.
Cavity wall insulation can be made out of three types of materials:
- mineral wool
- beads or granules
- foamed insulants.
All three are manufactured according to British standards. Foam Insulation systems should be certified by the British Board of Agrément and installed according to strict guidance laid out in the associated BBA Certificates.
